CUSHIONED v WHEEL.

Applieation ined April 9, 1920. serial Np. 372,454,

To all fre/omet may concern Be it known that I, AUsTIN A. lVlnNlDnN- HALL, a citizen of the United States, resid-- hub and rim of the wheel so that shocks and jars may be absorbed thereby without the annoyance and expense caused by blowouts and punctures.

Another object of this invention is the provision of cushioning anti-friction means between the cushioning means and the rim to reduce the wear on said cushioning means and further aid to the resiliency of the wheel.

A still further object of this invention' is the provision of a cushion wheel of the above stated character, which shall be simple, durable and efficient, and which may be manufactured and sold at a comparatively low cost.

lWith these and other objects in view as will become more'apparent as the description proceeds, the invention consists in certain novel Jfeatures of construction, combination, and arrangement of parts as will behereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to behad to the following vdescription and accompanying drawing, in which Figure 1 is a front elevation illustrating a cushioned wheel constructed in accordance with my invention,

2 is a vertical sectional view of the same,

. Fig. 3 is a transverse sectional view, illustrating the means of securing the pneumatic cushioning means to the hub and also the mounting of the anti-friction cushioning rollers.

Referring in detail to the drawing, the f an annular rim 3 provided at each edge with tire engaging flanges l adapted to. retain on the hub a shoe 5 and in which is located the usual pneumatic tube 6 for inflating said shoe.

Guard plates 7 and 8 are mounted on the hub 1 and project beyond the shoe 5 and are provided with a series of comparatively large openings 9 to receive bolts 10. The bolts 10 have journaled thereon anti-friction rollers 11 constructed of rubber or any other material suitable for the purpose and are adapted to contact with the shoe 5 as clearly shown in the drawing. The plate 7 is secured to the hub 1 in any desired manner, while the plate 8 is keyed to the hub as shown at 12 and also is detachably secured to said hub so that the same may be removed when desiring to inflate the inner tube or to remove the shoe 5 from the rim 3 for any purpose.

An outer tire supporting rim 13 supports a solid tire 14 constructed from rubber `or any other material suitable for the purpose and said rim 13 has formed thereon inwardly extending and relatively spa-Ced plates 15V provided with openings 16 to receive the bolts 10 and are positioned on each end of the roller, thus it will be seen thatthe outer rim 13 may have relative movement in relation to the hub 2 and is supported through the cushioning and antifriction rollers 11 and the pneumatic shoe 5 so that when the tire 14 engages obstructions or irregular places in the roadway, the shoe 5 will assume the shock and thereby provide a comparatively easy riding wheel that does not employ a pneumatic tire which engages the ground, thus obviating punctures and blow-outs. It is also to be noted that this wheel can be readily and conveniently assembled and disassembled when desired and that any of the parts can be readily removed and replaced in case such parts become worn orvmutilated.

While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination, and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.

Having thus described my invention what is claimed is:

A cushion wheel including a hub having a pneumatic cushioning element and a rim supporting a tire, relatively spaced inwardly than the diameter o1 the bolts to permit the extending annular plates formed on said hub and rim to have relative movement in rim2 bolts carried by said plates and prorelation to each other. jeeting beyond the same, rollers on said In testimony whereof I affix my signature 5 bolts and engaging the elushirlining elements, in presence of two Witnesses.

and guard plates securec to t ie hub on each side of the cushioning element and slidably AUSTIN A MENDENHALL' receiving the annular plates and having Witnesses: openings to receive the ends of the bolts, BERNICE CROWLEY, 10 said openings being of a diameter greater FLORENCE B. MENDENHALL.
